The Long Curve for Crude Oil Contracts

You mentioned that you still have a very long curve for crude oil contracts. Is there any kind of discussion or thoughts on how or when the crude oil may become a smaller smaller part of CME's business? I think what we are seeing is customers recognize that there's an energy transition and arc to change that takes different views on whether that arc is three years, 10 years or 30 years but this is an important question time back to your question earlier around battery metals.
